Subject: BulletSim: Fix crash on the destruction of physical linksets. While
 fixing the above, add methods to physical body and shape pointer wrapper so
 routines won't have to know that IntPtr.Zero means no physical instance. Fix
 problem with physical linksets failing after a few sits and unsits by
 properly restoring child prom positions for compound linksets after multiple
 selection and deselections.
